Related Products of 4744-50-7, In the next few decades, the world population will flourish. As the population grows rapidly and people all over the world use more and more resources, all industries must consider their environmental impact. 4744-50-7, name is 2,3-Pyrazinecarboxylic anhydride belongs to Pyrazines compound, it is a common compound, a new synthetic route is introduced below.
General procedure: A solution of substituted benzyl amine (10 mmol) and an acid anhydride (10 mmol) in glacial acetic acid (15mL) was heated under reflux for 4h. After the evaporation of the reaction mixture to dryness under reduced pressure, the residue was neutralised by a solution of sodium bicarbonate (4%) until effervescence ceased. The precipitate obtained was washed with water, dried and re-crystallised from an appropriate solvent.
The synthetic route of 2,3-Pyrazinecarboxylic anhydride has been constantly updated, and we look forward to future research findings.
